Description
IMPROVED UNION SYSTEM FOR PACKAGING
DESCRIPTIVE MEMORY
The present invention relates to a multilayer joining system, suitable for the manufacture of packages made of sheets, especially for foodstuffs. The multilayer joining system is especially suitable for the production of upright bags, suitable for the packaging of liquid foodstuffs, especially beverages.
STATE OF THE ART
Containers of groceries assembled from joining systems are known, especially upright bags or upright bags resting on the ground. Generally, the typical attachment systems for such upright bags are coated with adhesive and / or are coated by extrusion, metallic foils being present in particular as barrier layer carriers or as layers to improve the mechanical properties. Other layers of such laminates are layers of synthetic materials, which depending on their field of application can be configured in different ways. Until now, the use of materials that have produced from petroleum and / or that are not biodegradable or compostable is typical.
Binding systems of this type as well as upright bags and methods for the production of upright bags or other packaging systems are known in the state of the art, documents EP 2 223 866 A1, WO 2008/037447 or EP 0 600 502. The binding systems disclosed therein are not biodegradable, so that the packages produced from them can only be discarded or disposed of in a conventional manner, while discarding or disposal by composting is not possible. Simultaneously, these joining systems involve starting materials in which a lot of energy is consumed, such as metal sheets, and in addition they consume petroleum-based materials. However, it is also desired, especially in the field of foodstuffs, to avoid the use of ecologically tolerable or compatible materials and, in particular, to dispense with the use of metal foils (since they are produced with a high energy input and a high degree of energy consumption). other resources, such as water). In addition, a compostability would open a simple route for discarding, since in this case the sheets and containers can be reused in a corresponding way by means of waste disposal and processing systems, already highly developed. On the other hand, the use of materials based on renewable raw materials would not recharge the existing resources of hydrocarbons and would also represent a contribution to the improvement of the CO2 balance.
In WO 2009/005947 A1, WO 96/31303 A1, DE 202005011641 U1, JP2010069766A, CN2457074 and WO2008 / 037447 are
reveal packaging materials.
Object of the present invention
The present invention therefore has the object to indicate a joining system, especially suitable for the production of an upright bag, the joining system presenting the properties necessary for the production of such packages for food products, such as stability , tightness against liquids, gas permeability, etc., predominantly using ecologically compatible or biologically degradable materials.
BRIEF DESCRIPTION OF THE INVENTION
This object is achieved by a joining system according to claim 1. In the secondary claims 1 to 8, as well as in the following description, preferred configurations of this joining system are indicated. On the other hand, the present invention also provides a package for food products, which covers the joining system according to one of claims 1 to 8. It is preferable that this package for food products is an upright bag.
DETAILED DESCRIPTION OF THE INVENTION
The joining system according to the present invention has as its essential component a paper layer, as well as at least a barrier layer, characterized in that the joining system does not include any metal foil.
Other configurations of the joining system according to the invention and the advantages associated therewith are presented below. The additional layers, defined below, the materials preferably used for the layers, the thicknesses of the layers and other configurations, can each be combined in an arbitrary manner; The specific sequence of the layers, indicated below, of the binding system according to the invention serve for the description and illustration of the present invention, which however is not limited to specific examples of this type.
Paper layer:
The binding system according to the present invention has as its essential layer a paper layer. Typically, this paper layer has a thickness in the range of 150 to 15 μm, preferably 100 to 25 μm, more preferably 80 to 30 μm, such as approximately 35, 45 or 50 μm. According to the invention, any type of paper can be used, which includes papers with fillers or fillers such as kaolin, talcum, titanium dioxide, starches, calcium carbonate, etc. In the case of the paper used according to the invention, it may be unprocessed or processed paper, with the papers with very short fibers being preferred. Transparent papers, such as, for example, parchment paper, which is a paper made from finely ground cellulose, are also preferred.
The essential paper layer according to the invention is located relatively broadly on the layer of the binding system facing outward from the finished package for food products, and the paper layer to be used according to the invention, especially the layer paper parchment preferred paper, contributes in particular to the mechanical strength and rigidity of the joining system of the present invention. The preferred use of parchment paper further leads to the fact that, thanks to the transparency of this paper, different types of printing are possible in which the inner side of the parchment paper layer receives an impression, as they are possible for example counter-printing processes, in which the inward-facing side of the parchment paper layer is printed (in this case, the printed image is transparently outward, so that it is especially possible to prevent damage and wear (abrasion) on the outer side of the paper layer). In addition, the paper material of this layer can be provided with additional additives, such as absorption agents, etc. In this way it is possible to optimize the contribution of this layer to the set of properties of the joining system.
In addition, the use of layers of paper allows to make a contribution to the protection of the environment, as in paper production, which includes production of parchment paper, renewable raw materials intervene, so that here it is possible overall to improve the balance of. C02
Barrier layer:
On the other hand, the joining system according to the present invention has at least one barrier layer. In this case, and depending on the desired configuration for the joining system, various options are possible, both as to the type of barrier layer, the position of the barrier layer in the joining system as well as the number of barrier layers. The joining system of the present invention may have one or more barrier layers, such as one, two or three barrier layers. They can be differentiated in terms of their type and position in the joining system. For example, the barrier layer can be a layer of barrier material and / or a barrier layer with barrier property and / or a layer of varnish, as described in each case below.
Barrier material layer:
The first option is to provide a layer of barrier material on the inner side of the product container
of the paper layer described above. A layer of barrier material of this type according to the present invention preferably comprises a carrier layer with a layer, preferably applied by vaporization, of barrier material. Alternatively, it is also possible to apply the barrier material layer in the form of a varnish, as described below. In this case, the carrier layer constitutes the main component of the barrier, in that the layer, preferably applied by vaporization, of barrier material itself has a thickness of only a few Angstroms or the layer of varnish, provided as alternative, it is also manifestly thinner than the carrier layer. It is preferable that the carrier layer comprises as a main component a biodegradable material and / or that is made of renewable raw materials. The materials which are particularly suitable as a carrier layer for the layer of barrier material to be used according to the invention, comprise polylactic acid materials as well as cellulose glass. Polylactic acid materials are already used for sheet materials and containers, for example as mulch sheets or shopping bags. Other known fields of application of polylactic acids are disposable cutlery, straw stems and boxes with screw cap. Another preferred material for the barrier layer is cellulose glass, which is a material known under the designation cellulose hydrate or cellophane.
The preferred materials for the carrier layers of barrier material of the present invention in themselves have a certain
fitness as a barrier, especially against liquids. Typically, these layers of barrier carriers have a thickness of about 10 to 100 μm, preferably 12 to 50 μm, more preferably 15 to 40 μm, such as about 25 μm.
However, in order to secure the desired property as a barrier, it is necessary to provide the carrier layer defined above with a layer of barrier material. According to the invention, in this case, barrier layers applied by vaporization, in particular with a very thin layer (of a few Angstroms), can be used to ensure a desired barrier effect, especially against oxygen, C02, but also in front of the water vapor. Suitable barrier materials according to the invention comprise the layers applied by vaporization of (semi) metallic or (semi) metal oxides, for example aluminum, SiO2, Al2O3, or other oxides, mixed oxides or mixtures. In this case, the oxide materials are preferred, since in this way it is possible to dispense altogether with the application of a metal layer.
The layer of barrier material, applied by vaporization, is preferably applied on one of the sides of the carrier layer; however, it is also possible to apply this vaporization barrier on both sides of the carrier layer. It is preferable that the barrier, defined above, which covers the carrier layer and the barrier material layer applied by vaporization, is arranged in the joining system according to the invention in such a way that the barrier applied by vaporization is present. on the side of the carrier layer away from the paper layer. However, other configurations are also possible. It is common that, due to considerations regarding the production process (ie, referring to the sequence of application / introduction of the individual layers of the joining system), an arrangement is chosen that ensures that the barrier layer is covered as quickly as possible. possible by another layer, in order to protect this relatively delicate layer against possible damage that may occur in the further development of the production process.
According to the invention, it is preferred that the layer of barrier material defined above be applied to the paper layer initially described. In this way it is possible to apply between them the usual layers that improve adhesion, which typically have a thickness of less than 20 μm.; A thickness of 1 to 10 μ ??, in particular 2 to 5 μm, is particularly preferred. The person skilled in the art knows suitable materials and application types for layers of this type, and suitable examples include adhesive layers (extrusion adhesive, glue layer, etc.). Again, also in this case it is preferred that said materials for such adhesive layers are biologically degradable and / or are based on renewable raw materials.
In addition, and due to the smooth surface obtained during the manufacture of the film, the aforementioned preferred materials for the carrier layer such as lactic acid and cellulose glass materials, facilitate the application by vaporization, of very thin layers of barrier material , since in this case it is not necessary to create a large compensation for a rough surface of the carrier layer. At the same time the barrier materials described above adhere well to the carrier layer, in such a way as to ensure a safe production of the barrier layer covering the carrier layer and the layer, applied by vaporization, of barrier materials.
In addition to its barrier effect, this barrier layer also contributes to mechanical strength, but also to protection against ultraviolet radiation. Thanks to the use of filling materials and additive materials, it is possible to modify these properties to a greater degree and optimize them, for which usual materials known to the person skilled in the art can be used, for example as an absorbent of the ultraviolet radiation or filler materials to increase rigidity.
Another option for a barrier layer is a correspondingly shaped seal layer, which is described below.
Stamp coat:
On the other hand, the joining system according to the present invention encompasses a seal layer, which is applied to one of the sides of the barrier material described above. This seal layer is configured in such a way that it is next to the layer located at the most
internally possible of the essential layers of the binding system, that is, the seal layer is typically the inner layer of a finished package for food products. Also, the seal layer according to the present invention is preferably made of biodegradable or more preferably still compostable materials, and / or from materials based on renewable raw materials.
Polymer-based polymer materials are particularly preferred, for example the polylactic acid materials described above, but also PBAT (polybutylene adipate-terephthalate) and other similar materials, as well as mixtures thereof. For example, a material marketed by BASF under the designation Ecoflex ® is suitable.
It is preferable that the seal layer has a thickness of about 10 to 200 μm, preferably 20 to 150 μm, more preferably still 100 to 50 μm, such as about 90, 75 or 60 μm.
Again, the seal layer may be provided with additives and fillers, as described above for the other layers. Again, in this way it is possible to modify and optimize the properties of the joining system.
Again, in order to apply this seal layer securely on the above-described barrier layer, an adhesion enhancing layer, configured as described above in what presides, can be used. To further improve adhesion, it is also possible to use
additional techniques to improve the adhesion of the individual layers, such as surface treatments by flame or corona discharge methods, etc.
On the other hand, the seal layer described above can also be coated with barrier material, preferably by evaporation. In this respect, the aforementioned materials can be used; again, in this case, oxidite coatings, especially SiOx, AIOx, mixtures thereof and other oxides are especially preferred. Again, barriers of this type can be applied on one or both surfaces of the seal layer; usually, and also for reasons of cost, the application on one of the surfaces is sufficient. In some embodiments of the present invention, if the seal layer described herein encompasses a barrier coating of this type, it is possible to dispense with the layer of barrier material described above, since in this configuration the seal layer takes charge of the action as a barrier, in such a way that a layer structure with a paper layer and a layer is possible. However, in each case, sufficient properties as barrier and mechanical properties of the joint system as a whole are achieved. Again, thanks to the use of the polyester materials described above, it is ensured that the binding systems of the present invention consist essentially of materials that are essentially biologically degradable or that are compostable, which is preferable.
Another option of a barrier layer is a varnish layer, described below.
Varnish coat
Another option for a barrier layer is a varnish layer, which can be applied, for example, on the paper layer. Suitable examples of varnish layers are nitrocellulose-based varnishes. They can serve, for example, as barriers against the passage of moisture. The person with expertise in the specialty knows types of applications, layer thicknesses and materials, suitable, for layers of this type.
Adhesive layers
If necessary, between the layers described herein it is possible to provide layers of adhesive or glue to improve the adhesion, for which adhesive materials or adhesives known to the person skilled in the art are used, for example, extrusion adhesives. and the adhesive layers claimed above. In this case, the person skilled in the art knows suitable materials, and also in this case it should be noted that it is preferable that the materials for such adhesive layers are biodegradable and / or are based on renewable raw materials. preferably layers especially between a paper layer and a carrier layer, which is part
component of a layer of barrier material defined above. On the other hand, adhesive capable of being provided between the seal layer and the barrier layer can preferably be provided; again, in a preferred embodiment such an adhesive layer is provided between the seal layer and the carrier layer of the barrier material layer. However, in one option it is possible to provide a layer of adhesive between the paper layer and the barrier layer or between the seal layer and the barrier layer, such that this layer of adhesive is provided in contact with the layer of barrier material. Adhesive layers of this type improve the adhesion of the individual layers of the bonding system; however, they can also additionally contribute to the properties as a barrier, especially against oxygen permeation.
Lacquer rubber coating
Another option is to provide additional shellac layers, which essentially consist of shellac. Such shellac layers can be provided in arbitrary positions in the joining system; these layers preferably have a relatively low thickness, typically less than 20 μm, preferably from about 1 to 10 μm, more preferably from 2 to 5 μm.
Such shellac layers can be provided between the paper layer and the barrier layer, between the barrier layer and the seal layer, but also between the carrier layer and the barrier material layer. It is possible to provide one or more layers of shellac, in order to further improve the barrier action of the binding material according to the invention.
The options described herein for barrier layers can be used individually but also in combination in the joining system according to the invention, depending on the final purpose desired. The number of these layers can be chosen arbitrarily, and for example one, two, or three barrier layers, which may be the same or different from each other, may be present.
Therefore, as a whole, the present invention provides an improved joining system, suitable for the manufacture of containers for edible products, especially upright bags, being possible to dispense with the use of metal sheets, without influencing unfavorably on the barrier properties or on the mechanical properties, and using polymer materials based on essentially renewable raw materials and / or biodegradable.
In addition to the above-described essential layers and optional adhesion enhancing layers, the joining system of the present invention can also encompass additional layers, such as for example a varnish on the outer surface of the paper layer or another layer of seal on the inner and / or outer side of the joint system.
Therefore, the binding systems given by way of example can be structured as follows (from the inside out, referred to a container for food products):
Varnish / paper layer / adhesive / barrier material layer / adhesive / seal layer
Varnish / paper layer / adhesive / barrier material layer / adhesive / seal layer with barrier material I
Varnish / paper layer / adhesive / seal layer with barrier material
Paper coating / adhesive / barrier material layer / adhesive / seal layer
Varnish / paper layer / barrier material layer / seal layer t However, the present invention is not limited to these embodiments given by way of examples.
The joining system according to the present invention is particularly suitable for the production of packages for food products, especially for liquid or semi-liquid food products, preferably beverages, especially fruit juices and other fruit-based beverages. In spice, the joining system according to the invention makes it possible to manufacture an upright bag by conventional manufacturing processes, whereby it is possible to prepare bases for food products, which are essentially based on biodegradable raw materials or which can be discarded for disposal. Composted example.
